To all whom it may concern Be it known that we, EUGENE VONNEZ andCHARLES JA UEMOT, both citizens of the Confederation of Switzerland,residing at Geneva, Canton of Geneva, Confederation of Switzerland, haveinvented certain new and useful Improvements in Vehicle Bridges withMovable Rear Parts, of which the following is a specification.

The object of this invention is to provide a vehicle having a loadingbridge which is provided with a revoivable rear part whereby tofacilitate the loading and unloading of goods.

This application is a division of applicants copending application filedMar. 11, 1921, Serial No. 451,430.

The attached drawing shows by way of example one constructional form ofthe invention.

Figs. 1 and 2 are, respectively, a side view, and an end view, of thedevice according to invention,

According to Figs. 1 and 2 the illustrated embodiment of the inventioncomprises a loading bridge 38 carried by the frame 39 of an automobilevehicle, said bridge being provided at its rear part with a movableloading member 40 carried by supports 41, and adapted to oscillate on ashaft 42 arranged in bearings 112 placed on the lower part of the frame(Fig. 2). Said movable member 40 has, on its rear extremity, a Verticalwall or frame work 43. Its front end i. is provided with a bar 44towhich one end of a rope 114 is attached the other end being connected toa winch 17 (Fig. 1) whereby. when the movable member 40 is in theposition in which its platform constitutes a rear prolongation of thebridge 38 proper, the rope 114 is stretched tautly. The front part ofsaid movable member 40 is provided with an abutment 45, which, whenmember 40 is fully raised by means of the winch 17 and rope 114, strikesagainst a nose 46 of a bar 47 mounted upon a shaft 48 carried bysupports 49 fixed to the frame 39. The lower end of the bar 47 isconnected, by means of a rigid rod 50, to the upper end of a bar 51oscillating on a shaft 52. The lower end of bar 51 is in any knownmanner connected to a device, (not shown) for throwing the winch out ofgear (Fig. 1). The frame 39 carries a grooved roller 53, on supports 54.The rope 114 is guided in the groove or roller 53 whenever the movablemember 40 is lowered to the ground or is raised into its horizontalposition (Fig. 1).

The device is operated as follows If the movable member 40 is in theposition shown in full lines, in Fig. 1, and the winch 17 is thrown intogear, it will move in such a direction as to uncoil the rope 114 so thatthe movable member 40 due to its weight, describes an arc of a circleabout its shaft 42 as indicated by arrow B in Fig. 1. At the end of itscourse the wall or frame 43 comes to rest upon the ground and the winchis stopped in any desired manner. The goods or parcels which are to beconveyed by the automobile are then placed upon the wall or frame 43.This done the winch 17 is started again and caused to rotate in adirection opposite to that when uncoiling the rope 114. The latter nowbeing wound up, the member 40 and the goods loaded on the wall or framework 43 are smoothly lifted, and the goods, during the ascending motionof the member 40 are shifted by their own weight from the wall 43 ontothe platform. of the latter which at the end of its travel is on thesame horizontal plane as, and constitutes a portion of, the bridgeproper 39. After the goods or parcels are distributed on the front partof t e bridge 39 the manipulation described may be repeated until thebridge 39 is completely loaded.

It is evident that for unloading, the goods are shifted from the frontpart of the bridge onto the platform of the revolvable rear part and thelatter is lowered as in the former case for loading.

The abutment 45 on the front end of the movable part 40 will, wheneverthe member 40 is brought again to its initial position as in Fig. 1,strike against the nose 46 of the bar 47. By the intermediary of the{rod 50 fixed on its other end to the bar 51, a device (not shown) forthrowing the winch 17 out of gear, is operated. The action of the winch17 upon the rope 114 con nected to the movable member 40 thereuponimmediately ceases.

Having now described our invention, we declare that what we claim is 1.A loading device for vehicles, comprising. a loading platformpositionable on a vehicle, an operating winch on the Vehicle,

a shaft arranged crosswise and beneath the vehicle, a loading memberoscillable on said axle to a raised and a lowered position,' a cableconnecting the winch and the loading member, the loadin member being soarranged, that in its "raised position it forms a tail board to theloading platiorm, and also forms a regular portion of the loadingplatform proper.

2. A device as in claim 1, the portionof the loading platform formed bythe loading member, ,being the full Width of, and level and continuouswith, the platform proper. In testimony whereof We have signed our namesto this specification.
